Segments include Third World population anecdotes from experts in the field, a look at consumption trends, and an analysis of mass-media education efforts.

108. Race
When it comes to race, we might think that we're different because we look different. But if you look at DNA, the only things that distinguish us from one another are surface features such as the color of our skin. Segments include an investigation of why humans look so different on the outside when research has shown that the iconic markers for race really are skin-deep, and a demonstration in which Bill has his DNA sequenced.

109. Antibiotics
Since the 1980s, deaths from infectious diseases have increased. While much of this is due to new "bugs" such as HIV and hepatitis C, the alarming increase in antibiotic resistance is also responsible. Segments include a visit to the Centers for Disease Control and Prevention to discuss antibiotic drug resistance, a discussion of narrow-spectrum antibiotics and "bacteriocins," and an eye-opening demonstration of the impact of hand-washing on germs.

110. Genetically Modified Foods
Right now, more than half of the foods in your grocery store have been genetically modified in some way. Is genetic engineering safe for humans and the environment? Various sides of this controversial issue are presented—from traditional wheat breeders to organic, anti-pesticide researchers to corporate genetic engineering giants.

111. Transportation
Transportation is the single largest cause of air pollution. Segments include a historical retrospective on American car culture, a look at cutting-edge traffic simulation software, and the exciting promise of fuel-efficient cars and state-of-the-art hydrogen technology.

112. Global Climate Change
There's no question that the world is getting warmer. Are humans responsible or is this just part of a natural global cycle? Segments include a visit to the National Ice Core Laboratory in Denver to see how scientists identify and evaluate climate and atmospheric gases from 400,000 years ago; a demonstration showing how increased levels of C0² will affect temperatures on Earth, and a discussion of the role fossil fuels play in global climate change.

113. Evolution of Sex
Why sex? For one thing, with sex we're trying to stay ahead of the germs that are always attacking us. With one act of mixing our genes through sexual reproduction, there are millions of new possible combinations to help fight off the parasites. Segments include an explanation of the relationship between sex and parasites, an experiment in which women use scent to detect subtle genetic differences in men, and a discussion of the risks organisms take in reproducing sexually rather than asexually.

101. The Time Has Come (1964-66)
The insistent call for power is heard in the civil rights movement, lead by Malcolm X and the SNCC.

102. Crazy Horse & the Lakota Sioux Indians
From a young age, Crazy Horse was a famous warrior, but when his and Sitting Bull's bands wiped out Custer and his men at Little Big Horn, his fate was sealed. He was captured and killed by soldiers, but was secretly buried and is still venerated by his people.

103. Geronimo & the Apache Indians
The Apaches' ability to hide in the Chiricahua Mountains in Arizona had kept them free. A famous Medicine Man, Geronimo, and his band, stayed free long after American and Mexican invaders had defeated many of their tribe, but eventually he was captured and died in exile.

104. Quanah Parker & the Comanche Indians
Quanah Parker was born to a Comanche chief and his white wife, and for a while he led the Indians' fight against the early settlers. But, he then successfully adopted white ranchers' ways, living between two worlds and becoming famous in both.

101. Cheyenne: Indians of the Plains
With the Sioux, the Cheyenne dominated the western plains, hunted buffalo, and stayed free longer than other tribes. They were called the beautiful people for their appearance and colorful religious ceremonies. But the Sand Creek Massacre was the beginning of their defeat and decline.

102. Lakota Sioux: Indians of the Plains
The Lakota had been used to dominating the high plains country. As they lost much of their lands to white settlement, the Black Hills became their sanctuary. Then gold was discovered there, forcing Lakota and white Americans into warfare. Crazy Horse, Sitting Bull, and Black Elk are Sioux names that will be long remembered.

103. Seminoles: Indians of the Southeast
The Seminoles were a multicultural group of Native American and African American peoples who had fled into the Spanish territory of Florida. When the U. S. acquired Florida, Osceola and Billy Bowlegs led the fight to retain their lands. The tribe never officially surrendered.

104. Iroquois: Indians of the Northeast
Five warring Native American tribes, Mohawk, Oneida, Onondaga, Cayuga, and Seneca, negotiated the Great Law of Peace or Iroquois League, which influenced American political thinkers. Nonetheless, the American Revolution split the confederation, pitting old friends against each other and signaling the decline of their culture.

105. Navajo: Indians of the Southwest
Navajo ancestry has been traced to northwest Canada but they adapted well to their new desert environment. They resisted encroachment on their land by both the Spanish and the Americans, but eventually were defeated and transported. Still, many returned and their descendants live in their homeland today.

106. Shawnee: Indians of the Midwest

101. Many Planets, One Earth
The early Earth was a much different planet than the one we know today. Ancient rocks provide evidence of the emergence of oxygen in the atmosphere and of a frozen Snowball Earth.

102. Atmosphere
The atmosphere is what makes the Earth habitable. Heat-trapping gases allow ecosystems to flourish. While the NOAA Global Monitoring Project documents the fluctuations in greenhouse gases worldwide, MIT's Kerry Emanuel looks at the role of hurricanes in regulating global climate.

103. Oceans
Ocean systems operate on a range of scales, from massive systems such as El Niño that affects weather across the globe to tiny photosynthetic organisms near the ocean surface that take in large amounts of carbon dioxide. This program looks at how ocean systems regulate themselves and thus help maintain the planet's habitability.

104. Ecosystems
Scientists from the Smithsonian Center for Tropical Research document the astounding abundance of diversity in tropical rainforests to discover why so many species coexist that are competing for the same resources. In North America, the Yellowstone Wolf Reintroduction project explores why removing just one species dramatically changed the distribution of plants and animals up and down the food web.

105. Human Population Dynamics
The human population of our planet now exceeds 6.5 billion and is rising. Much of this growth is projected for the most environmentally fragile regions of the world. Will studying the history of the world's population growth help predict the Earth's "carrying capacity"?

106. Risk, Exposure, and Health
We all require food, air, and water to survive, which are contaminated to some extent by man-made pollutants. Two studies, one in a rural western mining town and another in a dense urban population, reveal how these exposures impact health, and what can be done to reduce the risks.

107. Agriculture
Will world population outrun food resources? The "Green Revolution" of the 20th century multiplied crop yields, in part through increasing inputs of pesticides and fertilizers. How can farmers reduce their use of agricultural chemicals and still produce enough food?

108. Water Resources
While essential to the lives of humans and animals, fresh water only accounts for six percent of the world's water supply. Scientists in Florida's Everglades and the water-challenged Southwest consider the optimum use of existing sources of fresh water for both humans and ecosystems.

109. Biodiversity Decline
Species are being lost at a rapid rate in rainforests and coral reefs. Yet many species still have not been discovered. Tropical scientists struggle to keep ahead of the bulldozers as they work to understand this complex ecosystem. And an ocean biologist predicts the death of life and the "rise of slime" in the sea.

110. Energy Challenges
Polluting the atmosphere with ever more carbon dioxide is not a viable solution for our future energy needs. Can new technologies such as carbon sequestration and ethanol production help provide the energy we need without pushing the concentrations of CO² to dangerous levels?

111. Atmospheric Pollution
Once released, air pollutants react chemically with each other under solar radiation to become even more dangerous secondary pollutants. A company in the Northeast U.S. tracks the emission of pollutants at street level, while an international long-term study follows plumes of pollution from Mexico City across the continent and beyond.

112. Earth's Changing Climate
Tropical glaciers are the world's thermometers; their melting is a signal that human activities are warming the planet. A California project tries to predict whether natural ecosystems will be able to absorb enough additional carbon dioxide from the atmosphere in the next 50 years to mitigate the full impact of human-induced greenhouse gas emissions.

113. Looking Forward: Our Global Experiment
Earth's essential systems are being stressed in many ways. There are many tipping points in the environment, beyond which there could be serious consequences. Will human ingenuity, resiliency, and cooperation save us from the worst outcomes of our global experiment?

Next, the products of photosynthesis are studied: the role of glucose in powering cellular respiration; and, the development of special organs to store starch. Experiments are presented demonstrating how to test for the presence of starch and how to measure the level of oxygen produced in photosynthesis.

103. The World of Bacteria [29:24]
This program uses photomicrographs to lead us into the world of bacteria. Where are bacteria found? How do bacteria grow? What do bacteria do to humans? This approach emphasizes key concepts from the National Science Education Content Standards, including cell structure and function, diversity and classification of living things, reproduction, genetics, evolution and ecology.

104. Understanding Evolution: Inheritance and Change [29:58]
This program explores evolution through natural selection. Students explore: variation in genes; the results of environmental pressure; best-adapted individuals, and the passing of genes to future generations. Students see how certain factors affect the frequency of alleles in a population, such as genetic drift, bottleneck and founder effect. The program also discusses divergent, convergent and parallel evolution as well as fossil dating methods.

105. Scientific Inquiry: Steps, Skills and Action [23:39]
How do you ask the "right" question in a scientific investigation? How do you use prediction to test a potential explanation? This program helps students appreciate the steps and skills involved in scientific inquiry--from initial observation, through refining a question to make it testable through building an explanation based on evidence.

106. Rising Threat of Infectious Diseases [26:28]
This program reveals how infectious diseases such as HIV or tuberculosis are an increasing danger to human beings.

108. Brain Scans: Alcohol and the Teenage Brain [22:43]
Utilized for training by Mothers Against Drunk Driving (MADD)
This program takes teens on a tour of several labs across the country including one at the University of California at San Diego where doctors are researching the effects of alcohol abuse in teenage brains. The show's host has a brain scan, and then has the chance to see how it compares with the brains of other teens who drink alcohol regularly. These ground-breaking studies dramatically connect long-term brain damage to underage drinking. Students will learn why alcohol seems to harm younger brains more profoundly than older ones.

109. Classification of Living Things [19:46]
There are millions of different species living today, and these represent a tiny fraction of all the species that have existed in the past. This program illustrates how over thousands of years people have been trying to find meaning and order in the diversity of life. Students learn that classifying living things has changed with the discovery of new kinds of organisms, and with our growing understanding of evolution and genetics. The program looks at the differences of each of the traditional five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. It then describes how this five-kingdom approach to classification has been modified as a result of recent discoveries about different types of bacteria. The program stresses that the ways we organize and categorize living things will continue to change in the future as new discoveries are made.

110. Biodiversity: The Web of Life [26:28]
From penguins in Antarctica to tree frogs in Costa Rica to E. coli bacteria in human intestines, this program focuses on the incredible variety of life on our planet and explores the biological processes at work in communities and ecosystems throughout the globe. Students see exotic footage demonstrating how life has adapted to all kinds of ecosystems--from the desert to the rain forest. Students will appreciate why biodiversity is so important to their own well-being, and will come to recognize how the rapid growth of the human population poses a variety of threats to other species. In addition, the program examines global efforts to protect biodiversity through habitat preservation, the protection of air and water quality, and--as a last resort--captive breeding.

101. Applications of Logarithms [22:32]
This program brings exponential and logarithmic functions to life.

As the problems are discussed, clear and vivid graphics are used to help students fully understand the properties of trigonometric functions that come into play.

103. Applications of Conic Sections [22:44]
A team of teens seeks to answer that age-old question, "What good is math in the real world?" Each of the conics is introduced by Professor McConical, a teacher from bygone days when math was thought of as all formulas and memorization. His stark definitions are vividly illustrated as the teens navigate through video segments and computer graphics. The conics are seen in action as we take a tour of architectural structures, astronomical phenomena, medical technology and more. Each application serves to reinforce students' understanding of locus definitions and reflective properties.

104. Desktop Realities [22:19]
Students will be taken on an entertaining excursion through a world where problems arise at every turn--problems that may involve fun and games, business and industry, or life and death. In each situation, it's mathematics to the rescue. Students are challenged to address the problems presented. In the process, they'll be exploring indispensable topics in secondary math, such as graphing techniques, geometry, probability, and analyzing functions.

105. ProMath: Crime Stoppers [25:37]
This program shows how math is used in every facet of law enforcement. Detectives, forensic scientists, prosecutors, defense attorneys, and other officials present stories where the tools of mathematics are invaluable.
